Since x=8y, subsitute 8y for x in other equation
y=6x-11
y=6(8y)-11
y=48y-11
minus y both sides
0=47y-11
add 11 to both sides
11=47y
divide both sides by 47
subsitute taht for y to find x
x=8y
in (x,y) form
(x,y)
y=6x-11
y=6(8y)-11
y=48y-11
minus y both sides
0=47y-11
add 11 to both sides
11=47y
divide both sides by 47
subsitute taht for y to find x
x=8y
in (x,y) form

Answer:
(6,-1)
Explanation:
The slope of the line can be calculated using the following formula:
slope =
We are given that:
slope = -0.75
point (x1,y1) is (-2,5)
We will use each of the given points to calculate the corresponding slope, then compare the calculated slope with the given one.
For point (6,-1):
slope =
= -0.75 ........> accepted choice
For point (2,8):
slope =
= 0.75 ........> rejected choice
For point (-5,1):
slope =
= 4/3 ........> rejected choice
For point (1,1):
slope =
= -4/3 ........> rejected choice
Therefore, the first option is the only correct one.
Hope this helps :)
